Abstract
Wallboard rivet nail extracting tool in boxcar. Pulling force hydro -cylinder, piston, spring are established to the rear end in the casing. Form thrust oil cylinder between pulling force piston rod and casing, have thrust piston, spring in it. The pulling force piston rod front end working head internal fixation pull rod of keeping silent, front end are kept silent about connecting with central connecting pin, the pin junction if left and right sides pull rod, the front end and the left and right sides are kept silent, rear end and casing pin junction. The pull rod of keeping silent has the distance rod with thrust piston interlock from top to bottom. The oil pump is outside, and the push -and -pull is advanced oil pipe and is introduced the hydro -cylinder from the handle of perpendicular to casing in. The work of pulling force jar, two keep silent rotates the embedding centre gripping or the cutting centre gripping rivet nail lantern ring, the work of thrust jar, the inside wallboard of distance rod antedisplacement is exerted pressure, extracts the lantern ring from the mounting hole. Solve the change of present interior wallboard traditional chinese clothing restoration plywood and dismantle inefficiency, dangerous. Provide special extracting tool, implementation structure is simple, convenient to use, safe and reliable, save labour laborsaving, dismantle efficient. Not only be used for the interior wallboard of box wagon, also can be used to other metal sheets and composite sheet rivet nail and dismantle.
Description
(1) technical field: the utility model box car lining pulling rivet extracting tool relates to a kind of extracting tool for the special pulling rivet between connected composite plate and metallic plate.Belong to riveted joint class (B21J) and the securing member class (F16B) of metal machining.
(2) background technology:
See Fig. 2, the lining of box car 24 forms by the composite plate 22 of rear side and the metal bead 23 of front side.Composite plate because of finishing have often dismounting may, so this non-metal board that need dismantle of tradition is screw with the main method be connected between metallic plate, although screw connects detachable, bonding strength is low, easily loosen, and easily comes off under goods collision.Connect according to pulling rivet common between existing two metallic plates being connected between this metallic plate that need dismantle with non-metal board, first under powerful rivet force effect, composite board just crushes easily, if even if in riveted joint, if desired also very difficult during dismounting.
Therefore, need to provide a kind of for there being the technology being convenient to rivet and dismantle of the lining pulling rivet of composite board for decoration in box car.At present, the P70 type box car lining newly made just have employed a kind of following clinching method: 1) see Fig. 2, the nail bar 20 of special pulling rivet is stretched backward through installing hole 25 on front side of lining.2), after filling foundary weight 21 on rear side of lining, the collar 19 stretches in installing hole and rivets with nail bar deformable squeeze on rear side of lining.After riveted joint, structure is shown in Fig. 2: figure and marks 20 for the rivet bar after breaking, and mark 19 is the collar after extruding, and mark 19a is collar head,
As mentioned above, the composite plate of decoration during this box car lining maintenance, need be changed, or when riveting nonconforming in an installation, all need dismounting lining pulling rivet, then again rivet.And existing lining pulling rivet extracting tool, sled, the mode of pounding can only be adopted to carry out, cannot convenient and strength-savingly dismantle.This sled, pound that mode dismantlement work efficiency is low, poor stability, and the foundary weight 21 of the outer surface of dismantling can not be reused.Therefore a kind of removal tool special for lining pulling rivet must be developed.
(3) summary of the invention:
The box car lining pulling rivet extracting tool that the utility model proposes and method, its object solves that existing lining pulling rivet extracting tool can only adopt sled, the mode of pounding is dismantled exactly, conveniently cannot pacify the problem of gold dismounting.There is provided a kind of for riveting removal tool special that the is nonmetal and pulling rivet of metallic plate.
Technical scheme is as follows:
Box car lining pulling rivet extracting tool, comprises oil pump and oil circuit control section, it is characterized in that:
Comprise and provide pressure oil by oil pump and the cutting pincers of exerting pressure to the pulling rivet collar, clamp vertical oil-feed portion of the handle with cutting, cutting pincers comprises as follows: in housing 1, pull action cylinder 6 is established in rear end, has the pulling piston 5 of the axial X movement be slidably matched with pull action cylinder in it; Tension spring 4 is equipped with in pulling piston rear end, and tension spring cylindrical is equipped with limiting block plug 3, and limiting block plug is contained in cylinder cap 2.Stretch out between the pulling piston bar 5A of pull action cylinder and housing radial direction, form push action cylinder 9A, be provided with the thrust piston 9 moved axially in it, be slidably matched between thrust piston and push action cylinder; Between periphery, thrust piston front end and this place's shell inner hole, thrust spring 10 is housed, periphery, thrust piston rear end has thrust oil-feed annular groove 9.1.Working head structure: establish jaw pull bar 13, jaw back end of tie rod screws in pulling piston bar 5A piston rod groove 5.2 foremost; Jaw pull bar has pull bar U-shaped mouth 13C foremost, and its inner clip press against the left jaw 15A and right jaw 15B that longitudinally Y arranges, and pull bar U-shaped mouth, left jaw is connected with right jaw in crossing center position with-individual vertical center connecting pin 14; Longitudinally left lever 16A and right pull bar 16B is established in Y both sides; U-shaped mouth is all opened in left and right pull bar front end, and connects left and right jaw two side ends with left and right front connecting pin 14a1,14b1 respectively; Left and right back end of tie rod also all opens U-shaped mouth, and is connected to housing with left and right rear connecting pin 14a2,14b2 respectively; Vertically Z establishes upper and lower two pieces of distance rods 12, and every block distance rod rear end 12.1 is inserted between thrust piston 9 front end thrust piston and pulling piston bar, and pulling piston rod outer surface to move axially with thrust piston and slide anteroposterior stretch.Oil-feed portion of the handle comprises: housing is fixed in handle 7 upper end 7.1, and pulling force cylinder oil inlet pipe 17 is communicated with thrust oil-feed annular groove with pulling force oil-feed annular groove through intracavity of handle respectively with thrust cylinder oil inlet pipe 18; And the control button 8 be equipped with on handle with outside oil pump and control section interlock.
The utility model beneficial effect:
1) according to the shape and size after the riveted joint of lining special dragging rivet, devise the removal tool special with the one such as distance rod, push-and-pull double hydraulic cylinder moving axially longitudinally rotating jaw structure, axial stretching force, realize clamping split special dragging rivet, extract, dismantling; Arrange oil inlet pipe in handle and control button; And the external pressure oil supply of the hand hydraulic tool of the existing maturation of combinative utilize and control system; Realize structure simple, esy to use, safe and reliable, save labor, removal efficiency is high.2) along with box car is produced in enormous quantities and later stage inner trim panels maintenance, during dismounting, removal tool special is used to be inexorable trend.And the domestic producer that there is no develops lining pulling rivet extracting tool at present, thus the exploitation of this extracting tool not only solve lining pulling rivet always cannot the problem of safe ready dismounting, and filled up domestic blank.3) this extracting tool not only in a large number for the lining pulling rivet of box car, and can be used for the dismounting that other is the pulling rivet of composite plate and metallic plate by riveted plating.
